Abstract
A terminal device has a controller and a memory medium. The controller receives the latest map data from an information center to update map data stored in the memory medium. For updating, a user selects map data to be updated from map data groups by designating a selection condition via an input device. Selection condition concern 'location,' 'area (area size),' and 'scale.' After map data which meets the designated condition is selected, the controller updates the selected map data. With the above arrangement, a selection operation is simplified. Also, the controller determines 'area' and 'scale' candidates (defaults) and recommends them to the user by displaying them in a display. The candidates are determined such that the total volume of selected map data falls within a predetermined volume. Looking at the displayed candidates, the user easily set appropriate selection conditions.
